PurposeThe purpose of this paper is to challenge the current educational methods taking place in Danish lower secondary school by introducing the concept of education for sustainable development (ESD) to help managers and teachers facilitate an action-oriented approach aimed at potentiating the level of sustainability and environmental awareness.Design/methodology/approachThis conceptual paper is based on the relevant literature and examines the necessity to move beyond traditional education curricula by offering a new practical sustainable framework for facilitating ESD at Danish lower secondary schools. A particular focus relates to evaluating and adopting sustainable approaches in the educational literature that is sufficiently sensitive to practical changes in Danish lower secondary teaching methods.FindingsWith the purpose of generating awareness about climate change and students’ ecological footprint to lower secondary school students in Denmark, it was found that embedding ESD in the Danish curriculum would be an important tool for this purpose. The authors outline practical recommendations for managers at the lower secondary school level.Originality/valueThis conceptual paper addresses the core issue of traditional education in Danish lower secondary schools by suggesting to adopt the educational framework of ESD. To this end, the authors have offered a variety of specific practical suggestions accordingly to how traditional education can be redesigned by focusing on action-oriented learning and future-oriented ESD. Furthermore, the authors propose that certain educational components of smart cities might promote an underlying commitment to meet the core issues of climate change, as this has yet to be examined. The research on ESD for managers at the Danish lower secondary school level is fairly limited to date.
